The VW3AE0117 is a 230 V undervoltage coil designed to trip the circuit-breaker in Schneider Electric Altivar floor-standing enclosures — specifically the Altivar 61 Plus, 61 Plus-LH, 71 Plus, and 71 Plus-LH ranges. It's a protection accessory, not a run coil: when supply voltage drops below the dropout threshold, it releases the breaker latch, killing power to the drive to prevent a brownout restart or uncontrolled motor re-acceleration.
What the 230 V rating means for fit
The coil is rated for a 230 V supply. It is designed to be wired into the control circuit that feeds the Altivar enclosure's breaker shunt trip.
